The MC74AC139/74ACT139 is a high–speed, dual 1–of–4 decoder/demultiplexer. The device has two independent decoders, each accepting two inputs and providing four mutually–exclusive active–LOW outputs. Each decoder has an active–LOW Enable input which can be used as a data input for a 4–output demultiplexer. Each half of the MC74AC139/74ACT139 can be used as a function generator providing four minterms of two variables.
